FIELD OF THE INVENTION

[0001] The present invention relates to a fabric, e.g. to be used toprovide reinforcement or cut-resistance to protective textiles, such ase.g. clothing, canvasses, tents and shelters.

[0002] The present invention relates more in particular to such fabrics,being woven and comprising steel cords in warp and/or weft direction.The present invention further relates to the use of such a fabric toprovide cut-resistance to protective textiles such as e.g. clothing,canvasses, tents or shelters. It further relates to canvasses andclothing, comprising such fabric.

BACKGROUND OF THE INVENTION

[0003] Fabrics with steel cords are widely known, as stab-resistantinserts comprising steel cords from WO9727769.

[0004] Further, canvas reinforcements comprising metal elements are alsoknown from WO9855682. This document teaches that several metal elements,separated from each other and being embedded in a polymer strip, may beadhered to the inner side of canvasses to provide reinforcement.

SUMMARY OF THE INVENTION.

[0005] It is an object of the invention to improve the resistanceagainst the cutting action of a knife or cutter of protective textile,which comprises a fabric as subject of the invention comprisingelongated steel elements.

[0006] According to the present invention, a fabric comprises a warp anda weft. The warp comprises different warp elements, laying in a samedirection, the so-called warp direction. The weft comprises differentweft elements, laying in a same direction, the so-called weft direction.Each warp and weft element follows a certain path through the fabric,being respectively a warp path or a weft path. According to theinvention, at least one warp element or one weft element, or both,comprise two or more elongated steel elements, which are in contactrelationship with each other.

[0007] Warp element is to be understood as one or more individualelements such as e.g. yarns, filaments, bundles of fibers, wires orcords, which follow the same path through the fabric in warp direction.Preferably, but not necessarily, all individual elements of a warpelement cross the weft elements of the fabric in an identical way. Weftelement is to be understood as one or more individual elements such ase.g. yarns, filaments, bundles of fibers, wires or cords, which followthe same path through the fabric in weft direction. Preferably, but notnecessarily, all individual elements of a weft element cross the warpelements of the fabric in an identical way.

[0008] “In contact relationship” is to be understood as two or moreindividual elements contacting each other almost continuously over theirlength, along a so-called contact zone. From time to time, the contactmay be slightly interrupted, due to small undulations or unevenness overtheir surface. The contact between the different individual elements ofa warp element, respectively weft element may also be interrupted incase these different individual elements cross the individual elementsof a weft element respectively warp element, in a non-identical way.

[0009] The applicant has found that the resistance of a protectivetextile comprising a fabric as subject of the invention with elongatedsteel elements is improved drastically in a cutting direction, notparallel to the elongated steel element, when more than one elongatedsteel elements are woven in the fabric in contact relationship with eachother. When elongated steel elements are present in the warp directionof the fabric, two or more elongated steel elements may be in contactrelationship with each other in warp direction. They act, so to say, astwin or multiple elongated steel elements. When the elongated steelelements are present in weft direction, two or more elongated steelelements may be in contact relationship with each other in weftdirection.

[0010] It was even found that the cut-resistance is improved when two ormore elongated steel elements are in contact relationship with eachother, compared to a same number of elongated steel elements, eachrunning individually through the fabric, not being in contactrelationship with adjacent elongated steel elements. So thecut-resistance can be improved, without adding additional elongatedsteel elements to the fabric. According to the present invention, theelongated steel elements in contact relationship may be identical or maydiffer from each other, e.g. comprising different wire diameters, havingdifferent cord constructions, being provided out of different steelalloys, or having different mechanical properties.

[0011] Since the fabric as subject of the invention is used to providecut-resistance and reinforcement to protective textiles, distancesbetween adjacent warp and weft elements preferably are relatively large.If these distances are too small, the protective textile will loose to alarge extend its textile characteristic, meanwhile the weight of thefabric will render the protective textile too heavy to be used.Therefor, a fabric comprising metal elements which is used to providecut resistance to protective textiles, have a “steel covering ratio Cs”,which is relatively low. Steel covering ratios of fabrics as subject ofthe invention may be less than 75%, preferably less than 60%, such asless than 40%, or even less than 30%.

[0012] This steel covering ratio Cs is the percentage of the fabric'ssurface in flat position, which is provided by the elongated steelelements in warp and/or weft direction.

[0013] When only one type of elongated steel element is present in warpdirection, and/or only one type of elongated steel element is present inweft direction, this steel covering ratio Cs is to be calculated usingthe formula:

Cs=(B*α*Da+A*β*Db−α*β*Da*Db)*100/A*B

[0014] Wherein

[0015] A=length of the fabric in warp direction

[0016] B=length of the fabric in weft direction

[0017] α=Number of elongated steel elements present in A

[0018] β=Number of elongated steel elements present in B

[0019] Da=diameter of elongated steel element in warp direction A

[0020] Db=diameter of elongated steel element in weft direction B

[0021] When n different types of elongated steel elements are present inwarp direction and/or m different types of elongated steel elements arepresent in weft direction, the formula reads as:

Cs=[B*(Σ_(n)α_(n) *Da _(n))+A*(Σ_(m)β_(m) *Db _(m))−(Σ_(n)α_(n) *Da_(n))*(Σ_(m)β_(m) Db _(m))]*100/A*B

[0022] Wherein

Σ_(n)α_(n) *Da _(n)=α₁ *Da ₁+α₂ *Da ₂+. . . +α_(n) *Da _(n)

Σ_(m)β_(m) *Db _(m)=β₁ *Db ₁+β₂ *Db ₂+. . . +β_(m) *Db _(m)

[0023] With “different types of elongated steel elements” is meant thatthe elongated steel elements differ from each other, e.g. comprisingdifferent wire diameters, having different cord constructions, beingprovided out of different steel alloys, of having different mechanicalproperties.

[0024] Elongated steel elements may be present in only the warp elementsor weft elements. It should be clear that, according to the invention,elongated steel elements present only in warp elements, only in weftelements or in both are to be present as more than one elongated steelelement, being in contact relationship with each other.

[0025] In case both in warp direction and weft direction elongated steelelements are in contact relationship with each other as subject of theinvention, it is not necessary that warp elements and weft elements haveto comprise the same number of elongated steel elements. Warp elementsand weft elements may comprise a different number of elongated steelelements. Also different warp elements and/or different weft elementsmay comprise a different number of elongated steel elements.

[0026] One understands that, according to the invention, differentweaving structures may be used. Also different distances betweenadjacent warp elements and weft elements may be used. Also differentelongated steel elements may be used in warp and weft direction. It iseven so that different elongated steel elements may be used to providethe elongated steel elements, which run either in warp elements or weftelements in contact relationship with each other.

[0027] Different elongated steel elements may be used to provide afabric as subject of the invention.

[0028] An elongated steel element to be used in either the weft or thewarp, or in both, can take following forms:

[0029] (a) a single steel wire;

[0030] (b) a bundle of non-twisted steel wires;

[0031] (c) a steel cord, i.e. a twisted structure with two or more steelwires.

[0032] These elongated steel elements all have following commonfeatures:

[0033] the wire diameter ranges from 0.03 mm to 0.60 mm, preferably from0.04 mm to 0.45 mm;

[0034] the steel composition is preferably a plain carbon steelcomposition, i.e. it generally comprises a minimum carbon content of0.40% (e.g. at least 0.60% or at least 0.80%, with a maximum of 1.1%), amanganese content ranging from 0.10 to 0.90% and a silicon contentranging from 0.10 to 0.90%; the sulphur and phosphorous contents areeach preferably kept below 0.03%;

[0035] additional micro-alloying elements such as chromium (up to 0.2 à0.4%), boron, cobalt, nickel, vanadium . . . may be added to thecomposition;

[0036] stainless steel compositions are, however, not excluded;

[0037] the carbon steel wires are preferably covered with a corrosionresistant coating such as zinc or such as a zinc alloy, e.g. analuminium-zinc alloy: the aluminium content may range from 2 to 12% inthe metallic fraction of the zinc alloy coating, e.g. from 4 to 6.5%,and is preferably about the eutectic value of 5%; a wetting agent ispreferably present in an amount sufficient to have wetting of thesubstrate steel by the zinc-aluminium alloy; amounts smaller than 0.1%are usually sufficient for the wetting agent. The wetting agent can becerium in an amount ranging from 0.01% to 0.05% and/or lanthanum in anamount ranging from 0.01% and 0.06%. All mentioned percentages are herepercentages by weight of the zinc alloy coating.

[0038] Organic coatings may be used to improve the adhesion from theelongated steel elements with polymer matrix material such as disclosedin WO-A1-99/20682 and WO-A1-99/55793.

[0039] If the elongated steel element is a steel cord, various existingsteel cord constructions may be used.

[0040] Examples here are:

[0041] multi-strand steel cords e.g. of the m×n type, i.e. steel cords,comprising m strands with each n wires, such as 4×7×0.10 or 3×3×0.18;the last number is the diameter of each wire, expressed in mm.

[0042] compact cords, e.g. of the 1×n type, i.e. steel cords comprisingn steel wires, n being greater than 8, twisted in only one directionwith one single step to a compact cross-section, such as 1×9×0.18 or1×12×0.18; the last number is the diameter of each wire, expressed inmm.

[0043] If these compact cords have a high twisting pitch, i.e. a laylength greater than hundred times the wire diameter, the cords can takea flat cross-section at the cross points between warp and weft, whichdecreases the thickness of the fabric. A person skilled in the artunderstands that this effect of decreasing is not limited to a specificnumber of steel cords either in warp or weft elements, or both. Thiseffect is also apparent when warp and/or weft comprises only one steelcord per warp and/or weft element.

[0044] layered steel cords e.g. of the I+m (+n) type, i.e. steel cordswith a core of I wires, surrounded by a layer of m wires, and possiblyalso surrounded by another layer of n wires, such as 2+4×0.18; the lastnumber is the diameter of each wire, expressed in mm.

[0045] single strand steel cords e.g. of the 1×m type, i.e. steel cordscomprising m steel wires, m ranging from two to six, twisted in onesingle step, such as 1×4×0.25; the last number is the diameter of eachwire, expressed in mm.

[0046] Open steel cords e.g. of the m+n type, i.e. steel cords with mparallel steel wires surrounded by n steel wires, such as disclosed inU.S. Pat. No. 4,408,444, e.g. a steel cord 2+2×0.25; the last number isthe diameter of each wire, expressed in mm.

[0047] The steel cord used in the context of the present invention maybe a steel cord with a high elongation at fracture, i.e. an elongationexceeding 4%, e.g. an elongation between 5% and 10%. High elongationsteel cord has more capacity to absorb energy.

[0048] Such a steel cord is:

[0049] either a high-elongation or elongation steel cord, i.e. amulti-strand or single strand steel cord with a high degree of twisting(in case of multi-strand steel cords: the direction of twisting in thestrand is equal to the direction of twisting of the strands in the cord:SS or ZZ, this is the so-called Lang's Lay) in order to obtain anelastic cord with the required degree of springy potential;

[0050] an example is a 3×7×0.22 High Elongation steel cord with laylengths 4.5 mm and 8 mm in SS direction;

[0051] or a steel cord which has been subjected to a stress-relievingtreatment such as disclosed in EP-A1-0 790 349; an example is a2×0.33+6×0.33 SS cord.

[0052] As an alternative or in addition to a high elongation steel cord,the steel cord may be composed of one or more wires which have beenplastically deformed so that they are wavy. This wavy natureadditionally increases the elongation. An example of a wavy pattern is ahelix or a spatial crimp such as disclosed in WO-A1-99/28547.

[0053] In order to calculate the steel covering ratio when steel cordsare used to provide a fabric as subject of the invention, the diameterof the steel cord is defined as the diameter of the smallest imaginarycircle, which circumscribe a radial section of the steel cord.

[0054] Next to elongated steel elements, synthetic or natural fiberyarns may be used to provide a fabric as subject of the invention,providing other protective characteristics to the fabric such as flameretardant properties and bullet-proof properties. Or such yarns may beused to fill the fabric structure by closing the openings between warpand weft elements comprising elongated steel elements. Fibers such aspolyaramid fibers, glass fibers, cotton or wool fibers, fibers frompolypropylene, polyethylene, polyester, polybezobisoxazole,poly(p-phenylene-2,6-benzobisoxazole), polybenzimidazole or polyacrylmay be used.

[0055] Fabrics as subject of the invention are to be used to reinforceor to provide cut-resistance to protective textiles. Protective textilesare to be understood in the largest way. Textiles protecting human oranimal bodies against cutting actions, e.g. protective vests are to beunderstood. A fabric as subject of the invention may be used as one ofthe textile fabrics, who are added one on top of the other, so providingthe protective functioning.

[0056] Also textile fabrics to be used as a base for seat coverings areto be understood.

[0057] Further, protective textiles may be used to provide e.g.canvasses, tents, shelters (e.g. for sheltering a passage between twotrain wagons), building textiles, dock-shelters, windable or foldablecurtains or tops of convertibles.

[0058] One or more textile layers, of which one is to be a fabric assubject of the invention may be added on top of the other and laminatedto each other.

[0059] Possibly, a polymer layer may be provided on one or both sides ofthe fabrics, in such a way that the polymer layer or layers adhere tothe fabric, e.g. by calandering, laminating or extrusion. A protectivetextile is provided in this way. Also protective canvasses, to be usede.g. on trucks, containers or trains are to be understood as protectivetextiles. A fabric as subject of the invention is inserted between twoor more layers of polymer and e.g. calandered or laminated between them,or a fabric as subject of the invention may be coated on one or bothsides with a polymer layer, e.g. by extrusion.

[0060] When polymer layers are provided on both sides of the fabric assubject of the invention, best result as far as improvement ofcut-resistance were obtained when the adherence of the polymer with thesteel of the elongated steel element is reduced to a minimum at thecontacting zone of two or more elongated steel elements being in contactrelationship with each other.

[0061] Canvasses for different uses may be provided using a fabric assubject of the invention. E.g. canvasses for trucks comprising a fabricas subject of the invention may be of the curtain type or of the roll-uptype. Canvasses of the curtain type are slidingly suspended onhorizontal rails and can be horizontally slid to one side to open thecanvas. Canvasses to the curtain type require flexibility in thehorizontal direction. Canvasses of the roll-up type can be rolled upvertically to open the canvas. Canvasses of the roll-up type requireflexibility vertically. Different elongated steel elements may be usedto provide a fabric as subject of the invention, still providing thenecessary flexibility in horizontal or vertical direction, howeverproviding sufficient cut-resistance or reinforcement in both horizontaland vertical direction.

[0062] Different polymers may be used to provide protective textilessuch canvasses, e.g. silicon-based polymers, polyurethane, polyamide,polyvinylchloride, synthetic or natural rubbers, polyesters orpolytetrafluorethylene.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0069]FIG. 1 shows a fabric 10 to be used to provide reinforcement orcut-resistance to protective textile, comprising elongated steelelements as known in the art. Elongated Steel elements 11 are woven intoa plain-woven structure, having warp elements 12 and weft elements 13.Each warp element and weft element comprises one elongated steel element11, which has its own path through the fabric. Between adjacent warpelements a distance 14 is provided. Between adjacent weft elements adistance 15 is provided.

[0070] A fabric as subject of the invention is shown in FIG. 2. A fabricas subject of the invention may be a plain-woven fabric 20, comprisingwarp elements 21 and weft elements 22. According to the invention,either warp elements 21 or weft elements 22, or both, comprise more thanone elongated steel element 23, being in contact relationship with eachother. In the present embodiment, a fabric as subject of the inventionis shown, of which warp elements and weft elements comprise twoelongated steel elements. Between adjacent warp elements a distance 24is provided. Between adjacent weft elements a distance 25 is provided.

[0071] A clear and drastically improvement of the cut-resistance wasnoticed between a protective textile comprising a fabric 10 as known inthe art, and a comparative protective textile comprising a fabric 20 assubject of the invention. A cut-resistance comparative test was executedas follows.

[0072] Four different protective textiles were provided by laminatingtwo sheets of polyurethane to a fabric which is to providecut-resistance to the protective textile, said protective textile beinguseful as a protective canvass. Each sheet of polyurethane has athickness of 175 μm. Sample I and II are protective textiles, comprisinga fabric as subject of the invention. These fabrics had a weavingstructure as shown in FIG. 2. Sample III and IV are protective textiles,comprising a fabric as was known in the art. These fabrics had a weavingstructure as shown in FIG. 1. More information on the samples I to IV isto be found in table A. It should be noticed that all samples comprise asame number of elongated steel elements per surface unit. Sample I andII, and sample II and IV comprise the same elongated steel elements.Sample I and III have the same steel covering ratio. Sample II and IValso have an identical steel covering ratio. For all samples, nodifference for cut resistance was noticed in warp and weft direction.

[0073] All four samples were subjected to a cut-resistance test. FIG. 3provides a schematic view of the test set-up. A part of protectivetextile 31 is clamped with clips 32, in order to fix the protectivetextile vertically. The dimensions of the protective textile part areapproximately 230 mm by 310 mm. The protective textile part is hung to aframework 33. A pre-cut 34 of approximately 50 mm is made. A knife 35with a straight edge pointing downwards is inserted in the pre-cut andmoved downwards (as indicated by arrow 36). The force necessary to movethe knife downward over a distance of 250 mm through the protectivetextile is registered by a measuring system 37. Each time the knifemeets an elongated steel element, the force to continue the movementdownward increases until the elongated steel element is cut. A“saw-shaped” curve ‘force-distance’ is obtained which has severalmaxima, one maximum for each elongated steel element, which is cut. Anaverage of these maxima is calculated. For each test, a new knife 35 isto be used.

[0074] For these samples, a force as shown in table B was measured as anindication for the cut-resistance. Forces were measured when cuttingboth warp elements and weft elements. Equal forces were measured duringtests in warp and weft cutting direction, since both warp and weft wereidentical.

[0076] It is clear that when a fabric as subject of the invention isused, the cut-resistance is improved drastically. Even when the totalcontent of elongated steel elements and the steel covering ratio in theprotective textile was kept equal.

[0077] An alternative fabric as subject of the invention, and morepreferably used for protective garment is a plain-woven fabric 20, asshown in FIG. 2, comprising warp elements 21 and weft elements 22 beingsteel cords with construction 12×0.18. for each warp element and weftelement, two steel elements are in contact relationship with each other.Between adjacent warp elements a distance 24 of 4 mm is provided.Between adjacent weft elements a distance 25 of 4 mm is provided,providing a steel covering ratio of 70%.

[0078] In general, it was noticed that, when either a warp element or aweft element had to be cut, the cut-resistance could be improved byproviding two or more elongated steel elements, being in contactrelationship with each other.

[0079] Other embodiments of a fabric as subject of the invention areshown in FIGS. 4 to 6.

[0080] As shown in FIGS. 4a and 4 b, the cut-resistance may only beimproved in one direction. FIG. 4a shows a plain-woven fabric, with warpelements 41 and weft elements 42. Each weft element 42, being on adistance 44 from each other, comprises two elongated steel elements 43.Each warp element, being on a distance 43 from each other, comprises oneelongated steel element. All individual elements 43 of the weft elementcross the warp elements identically.

[0081] In FIG. 4b, an alternative embodiment is shown, where theindividual elements 43 of the weft elements cross the warp elements nonidentically. One understands that the individual elements of the warpand/or the weft elements may cross the individual elements of the weftrespectively the warp element in many different ways, so providingdifferent embodiments of a fabric according to the invention.

[0082] A preferred embodiment is provided when elongated steel elementsof type 3×3×0.18 multi-strand steel cords are used to provide a fabricas shown in FIG. 4a or 4 b, with distance 43 being 5 mm and distance 44being 10 mm. A steel covering ration of 27.5% is obtained

[0083] Alternatively, either all or some of the warp elongated steelelements 41 may be replaced by polymer yarns, such as polyamide-fiberyarns to provide an alternative embodiment of a fabric as subject of theinvention. As shown in FIG. 5, the cut-resistance may be improved to alarger extend either in warp or weft direction. FIG. 5 shows aplain-woven fabric, comprising warp elements 51 and weft elements 52,warp elements and weft elements being on a distance of respectively 53and 54. Warp elements may comprise a different number of elongated steelelements 55 than weft elements.

[0084] As shown in FIG. 6, each warp element does not have to comprisethe same number of elongated steel elements. Neither each warp elementdoes have to comprise the same number of elongated steel elements. Asshown in the embodiment of FIG. 6, warp elements 61 and weft elements 62may comprise different number of elongated steel elements.

[0085] The fabrics as subject of the invention may be used to providecut-resistance or reinforcement for protective textiles. As shown inFIG. 7, a fabric 71 as subject of the invention may be used to providecanvasses. The fabric 71 is laminated between two layers of polymer 72and 73, e.g. Polyurethane with thickness of 0.5 mm each. In theembodiment as shown in FIG. 7, only the warp or the weft elementscomprise two elongated steel elements 74 according to the invention.
